Description

Title: Macroscopically homogeneous cosmetic composition with an aqueous phase and an oily phase, a volatile hydrocarbon oil and a silicone elastomer containing carboxylic acid functions

Technical field

[0001 ] The present invention aims to provide, for the field of caring for and/or making up keratin materials, in particular the skin, a new macroscopically homogeneous composition comprising a) an oily phase comprising at least one volatile hydrocarbon oil, b) an aqueous phase and c) at least one silicone elastomer containing carboxylic acid functions.

[0002] Cosmetic makeup compositions are commonly used to give an aesthetic colour to keratin materials such as the skin, but also to enhance the beauty of irregular skin, by making it possible to hide marks and dyschromias, and to reduce the visibility of relief imperfections such as pores and wrinkles and also spots and acne marks.

[0003] Consumers are also looking for care and/or makeup products for keratin materials, in particular the skin, which have a texture that is comfortable from a sensory point of view and on application, in particular which are easy to take up and which spread easily over the area of keratin material to be covered.

[0004] Compositions comprising an oily phase and an aqueous phase forming a macroscopically homogeneous mixture (the distinction between the two mutually immiscible phases being impossible to see with the naked eye) such as oil/water emulsions, water-in-oil emulsions or bigels are galenic forms that are highly sought after by consumers for their creamy or gelled texture, their ease of application to the skin and their sensoriality in cosmetics, such as freshness, in the care field, in particular in anti-sun compositions, in anti-ageing compositions and in makeup such as foundations.

[0005] Published documents WO2015066161 (US20160200876), WO2015066165, WO201 5066199, WO2015167963, WO20180165434 (US10918587B2), IPCOM000250448D and IPCOM000250657D have already proposed makeup compositions based on silicone elastomers containing carboxylic acid functions exhibiting good performance in terms of wear property and durability. However, these polymers generally have a texture which is difficult to take up and apply and have a tendency to give makeup compositions of which the consistency does not make it possible to take up and spread the product easily on the skin. When they are used in compositions based on an oily phase and an aqueous phase forming a macroscopically homogeneous mixture such as emulsions, these silicone elastomers tend to produce formulations which are unstable over time and for which phase separation is observed.

[0006] The objective of this invention is to produce a macroscopically homogeneous care and/or makeup composition comprising an oily phase and an aqueous phase and comprising at least one silicone elastomer containing carboxylic acid functions, which is stable, has a consistency that is sufficient, flexible and homogeneous so as to be taken up and easily spread on the skin and which has good sensory properties such as freshness and lightness during application.

[0007] In addition, the applicant has observed that the composition according to the invention also makes it possible to obtain a water-releasing effect during application to the skin with the formation of droplets during spreading, with also good stability over time.

[0008] In the course of its research, the applicant has discovered unexpectedly that this objective can be achieved with a composition for caring for and/or making up keratin materials, in particular the skin, comprising, preferably in a physiologically acceptable medium: a) an oily phase comprising at least one volatile hydrocarbon oil Hi ; and b) an aqueous phase; and c) at least one silicone elastomer containing carboxylic acid functions; said composition having a product of the weight ratios [A] X [B] ranging from 0.07 to 0.21 with

[A] denoting the weight ratio of the amount of silicone elastomer relative to the total weight of the composition to the total amount of volatile hydrocarbon oil(s) relative to the total weight of the composition;

[B] denoting the weight ratio of the amount of aqueous phase relative to the total weight of the composition; said oily and aqueous phases forming therein a macroscopically homogeneous mixture. [0009] The compositions according to the invention are stable over time and have a consistency that is sufficient, flexible and homogeneous so as to be taken up and easily spread on the skin. They also have a feeling of freshness and lightness during application. [0010] This discovery forms the basis of the invention. [0011] The present invention relates to a composition for caring for and/or making up keratin materials, in particular the skin, comprising, preferably in a physiologically acceptable medium: a) an oily phase comprising at least one volatile hydrocarbon oil H1; and b) an aqueous phase; and c) at least one silicone elastomer containing carboxylic acid functions; said composition having a product of the weight ratios [A] X [B] ranging from 0.07 to 0.21 with [A] denoting the weight ratio of the amount of silicone elastomer relative to the total weight of the composition to the total amount of volatile hydrocarbon oil(s) relative to the total weight of the composition; [B] denoting the weight ratio of the amount of aqueous phase relative to the total weight of the composition; said oily and aqueous phases forming therein a macroscopically homogeneous mixture. [0012] The invention also relates to a process for coating keratin materials, more particularly for making up and/or caring for keratin materials, such as the skin, characterized in that it comprises the application to keratin materials of an emulsion as defined above. [0013] The invention more particularly relates to a process for making up and/or caring for the skin, characterized in that it comprises the application to the skin of a composition as defined above. Definitions [0014] In the context of the present invention, the term "keratin materials" means the skin and more particularly the areas such as the face, the cheeks, the hands, the body, the legs and thighs, the area around the eyes, and the eyelids. [0015] The term “physiologically acceptable” means compatible with the skin and/or its integuments, which has a pleasant colour, odour and feel, and which does not cause any unacceptable discomfort (stinging or tautness) liable to discourage the consumer from using this composition. [0016] For the oily and aqueous phases of the composition of the invention, the expression "that they form a macroscopically homogeneous mixture” is intended to mean the fact that observation of the composition with the eye does not make it possible to distinguish the presence of the two mutually immiscible phases. The identification of each of the two phases, and the arrangement and distribution thereof within the composition can generally be observed only under a microscope. Oily phase [0017] The composition according to the invention for caring for and/or making up keratin materials comprises at least one fatty phase comprising at least one volatile hydrocarbon oil H1. [0018] The term “oil” refers to a fatty substance that is liquid at ambient temperature (25°C) and atmospheric pressure (760 mmHg, i.e.10⁵ Pa). [0019] The term "oily phase" refers to an organic phase that is liquid at ambient temperature (25°C) and atmospheric pressure containing at least one oil and optionally the cosmetic additives which are soluble or miscible in said phase. [0020] The term “hydrocarbon oil” refers to an oil mainly containing carbon and hydrogen atoms and possibly one or more functions chosen from hydroxyl, ester, ether and carboxylic functions. [0021] For the purposes of the invention, the term “volatile oil” refers to any oil that is capable of evaporating on contact with the skin in less than one hour, at ambient temperature and atmospheric pressure. The volatile oil is a volatile cosmetic compound, liquid at ambient temperature, having in particular a non-zero vapour pressure, at ambient temperature and atmospheric pressure, in particular having a vapour pressure ranging from 2.66 Pa to 40000 Pa, especially ranging from 2.66 Pa to 13000 Pa and more particularly ranging from 2.66 Pa to 1300 Pa. [0022] Examples of volatile hydrocarbon oils H₁ which can be used in the oily phase of the composition of the invention include hydrocarbon oils having from 8 to 16 carbon atoms, and in particular C8-C16 isoalkanes of petroleum origin (also called isoparaffins) such as isododecane (also called 2,2,4,4,6-pentamethylheptane), isodecane and isohexadecane. Mention may also be made of the oils sold under the trade names Isopar® or Permethyl®, branched C8-C16 esters, isohexyl neopentanoate, and mixtures thereof. Other volatile hydrocarbon oils, for instance petroleum distillates, notably those sold under the name Shell Solt by Shell, may also be used. [0023] The volatile hydrocarbon oils H1 which can be used in the compositions according to the invention can be chosen from volatile linear alkanes comprising from 6 to 14 carbon atoms. [0024] Mention may be made, by way of examples of linear alkanes suitable for the invention, of the alkanes described in the patent applications WO 2007/068371 and WO 2008/155059 of Cognis (mixtures of different alkanes differing by at least one carbon). These alkanes are obtained from fatty alcohols, themselves obtained from coconut oil or palm oil. [0025] Mention may be made, by way of examples of linear C₆-C₁₄ alkanes suitable for the invention, of n-hexane (C6), n-heptane (C7), n-octane (C8), n-nonane (C9), n- decane (C10), n-undecane (C11), n-dodecane (C12), n-tridecane (C13), n-tetradecane (C14) and mixtures thereof. [0026] Mention may notably be made of n-dodecane (C₁₂) and n-tetradecane (C₁₄) sold by Sasol under the references, respectively, Parafol 12-97® and Parafol 14- 97®, and also mixtures thereof. [0027] According to another embodiment, a mixture of n-dodecane and of n- tetradecane is used. It is in particular possible to use the dodecane/tetradecane mixture in the 85/15 weight ratio sold by Biosynthis under the reference Vegelight 1214®. [0028] According to yet another embodiment, use is made of a mixture of volatile linear C9-C12 alkanes with the INCI name: C9-12 Alkane, such as the product sold by the company Biosynthis under the reference Vegelight Silk®. [0029] According to yet another embodiment, use is made of a mixture of n- undecane (C11) and of n-tridecane (C13), like those obtained in examples 1 and 2 of the application WO 2008/155059 from Cognis and like that sold under the trade name Cetiol Ultimate® by BASF. [0030] According to one particularly preferred embodiment, the volatile hydrocarbon oil H1 will be chosen from C8-C16 isoalkanes of petroleum origin, and more particularly isododecane. [0031] According to a preferential embodiment of the invention, the oily phase is present in the composition in an amount ranging from 5% to 95% by weight, and more preferentially from 10% to 90% by weight relative to the total weight of the composition.

[0033] The aqueous phase comprises water and optionally water-soluble or water- miscible ingredients, such as water-soluble solvents.

[0034] A water suitable for the invention can be a floral water, such as cornflower water, and/or a mineral water, such as Vittel water, Lucas water or La Roche-Posay water, and/or a thermal water.

[0035] In the present invention, the term “water-soluble solvent” denotes a compound which is liquid at ambient temperature and water-miscible (miscibility in water of greater than 50% by weight at 25°C and atmospheric pressure).

[0036] The water-soluble solvents which can be used in the composition of the invention can additionally be volatile.

[0038] According to a preferential embodiment, the weight ratio of the total amount of volatile hydrocarbon oil(s) relative to the total weight of the composition to the amount of aqueous phase relative to the total weight of the composition is greater than 0.085.

[0039] According to one particular form, the water is present in a concentration ranging from 5% to 95% by weight, and more particularly from 10% to 90% by weight, relative to the total weight of said composition.

[0043] The term "organopolysiloxane elastomer" means a supple, deformable organopolysiloxane that has viscoelastic properties and especially the consistency of a sponge or a supple sphere. Its modulus of elasticity is such that this material withstands deformation and has limited stretchability and contractibility. This material is capable of regaining its original shape after stretching. In general, it is partially or completely crosslinked and is not cyclic.

[0044] The term “silicone elastomer containing carboxylic acid functions” means an organopolysiloxane elastomer comprising in its structure at least two carboxylic acid groups with at least one -COOH function.

[0045] The composition according to the invention advantageously has a content of active material of silicone elastomer containing carboxylic acid functions ranging from 2% to 25% by weight relative to the weight of the composition. Preferably, this content ranges from 5% to 20% by weight relative to the weight of the composition.

[0046] The silicone elastomers containing carboxylic acid functions that can be used in the compositions of the invention can be chosen from those described in published documents WO2015066161 (US20160200876), WO2015066165, WO2015066199, WO201 5167963, WO20180165434 (US10918587B2), IPCOM000250448D, and IPCOM000250657D.

(A)Silicone resin

[00113] The nomenclature of silicone resins (also known as siloxane resins) is known under the name “MDTQ”, the resin being described as a function of the various siloxane monomer units it comprises, each of the letters “MDTQ” characterizing a type of unit. [00114] The letter "M" represents the monofunctional unit of formula R1R2R3SiO_1/2, the silicon atom being bonded to only one oxygen atom in the polymer comprising this unit. [00116] The letter "D" signifies a difunctional unit R1R2SiO_2/2 in which the silicon atom is bonded to two oxygen atoms. [00117] The letter "T" represents a trifunctional unit of formula R1SiO3/2. [00118] Such resins are described, for example, in the Encyclopedia of Polymer Science and Engineering, vol.15, John Wiley & Sons, New York, (1989), pp.265- 270, and US 2676182, US 3627851, US 3772247, US 5248739 or US 5082 706, US 5319040, US 5302685 and US 4935484. [00119] In the units M, D and T defined previously, R, namely R1, R2 and R3, represents a hydrocarbon radical (especially alkyl) containing from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or a hydroxyl group. [00120] Finally, the letter "Q" signifies a tetrafunctional unit SiO4/2 in which the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the remainder of the polymer. [00121] Various silicone resins with different properties can be obtained from these different units, the properties of these polymers varying as a function of the type of monomer (or units), of the nature and number of the R radical, of the length of the polymer chain, of the degree of branching and of the size of the pendent chains.

[00125] As silicone resins comprising MQ siloxysilicate units, mention may also be made of phenylalkylsiloxysilicate resins, such as phenylpropyldimethylsiloxysilicate (Silshine 151® sold by the company General Electric). The preparation of such resins is notably described in patent US 5817302.

Polymethylsilsesquioxane resins that may preferably be used are those in which R represents a methyl group, for instance those sold: - by the company Wacker under the reference Resin MK®, such as Belsil PMS MK®: polymer comprising CH3SiO3/2 repeating units (T units), which may also comprise up to 1% by weight of (CH3)2SiO2/2 units (D units) and having an average molecular weight of about 10000 g/mol, or - by the company Shin-Etsu under the reference KR-220L®, which are composed of T units of formula CH₃SiO_3/2 and contain Si-OH (silanol) end groups, under the reference KR-242A®, which comprise 98% of T units and 2% of dimethyl D units and contain Si-OH end groups, or else under the reference KR-251®, comprising 88% of T units and 12% of dimethyl D units and contain Si-OH end groups.

The data are processed on the basis of the conventional Mie scattering theory. This theory is the most suitable for size distributions ranging from the submicronic to multimicronic; it makes it possible to determine an “effective” particle diameter.

[00160] The pigments which can be used according to the invention can also be organic pigments.

[00161] The term “organic pigment” refers to any pigment that satisfies the definition in Ullmann’s encyclopedia in the chapter on organic pigments. The organic pigment may notably be chosen from nitroso, nitro, azo, xanthene, quinoline, anthraquinone, phthalocyanine, metal-complex type, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyrrole, thioindigo, dioxazine, triphenylmethane or quinophthalone compounds.

[00163] These pigments can also be in the form of composite pigments as are described in Patent EP 1 184 426. These composite pigments can be composed in particular of particles comprising an inorganic core at least partially covered with an organic pigment and at least one binder providing the fixing of the organic pigments to the core.

[00164] The pigment can also be a lake. The term “lake” is understood to mean insolubilized dyes adsorbed onto insoluble particles, the assembly thus obtained remaining insoluble during use.

[00165] The inorganic substrates onto which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium.

[00166] Mention may be made, among the organic dyes, of cochineal carmine. Mention may also be made of the products known under the following names: D&C Red 21 (Cl 45 380), D&C Orange 5 (Cl 45 370), D&C Red 27 (Cl 45 410), D&C Orange 10 (Cl 45 425), D&C Red 3 (Cl 45 430), D&C Red 4 (Cl 15 510), D&C Red 33 (Cl 17 200), D&C Yellow 5 (Cl 19 140), D&C Yellow 6 (Cl 15 985), D&C Green 5 (Cl 61 570), D&C Yellow 10 (Cl 77 002), D&C Green 3 (Cl 42 053), D&C Blue 1 (Cl 42 090).

[00171] A composition according to the invention may also comprise at least one liposoluble dyestuff, preferably in a proportion of at least 0.01 % by weight relative to the total weight of the composition.

[00172] Within the meaning of the invention, the term “liposoluble dyestuff” is understood to mean any natural or synthetic, generally organic, compound which is soluble in an oily phase or solvents miscible with a fatty substance and which is capable of imparting colour.

[00173] For obvious reasons, this amount is liable to vary significantly with regard to the desired intensity of the colour effect and to the colour intensity provided by the dyestuffs under consideration, and its adjustment clearly falls within the competence of those skilled in the art.

[00174] Mention may in particular be made, as liposoluble dyes suitable for the invention, of synthetic or natural liposoluble dyes, such as, for example, DC Red 17, DC Red 21 , DC Red 27, DC Green 6, DC Yellow 11 , DC Violet 2, DC Orange 5, Sudan red, carotenes ([3-carotene, lycopene), xanthophylls (capsanthin, capsorubin, lutein), palm oil, Sudan brown, quinoline yellow, annatto or curcumin.

Water-soluble dyestuffs [00175] A composition according to the invention may also comprise at least one water- soluble dyestuff, preferably in a proportion of at least 0.01 % by weight relative to the total weight of the composition.

Cosmetic compositions

[00178] The present invention also relates to a cosmetic composition comprising, in a physiologically acceptable medium, a composition as defined above.

[00179] The term “physiologically acceptable medium” is understood to denote a medium which is particularly suitable for the application of a composition of the invention to the skin.

[00180] The physiologically acceptable medium is generally suited to the nature of the support onto which the composition has to be applied, and also to the appearance under which the composition has to be packaged.

[00181 ] The compositions of the invention may be in the form of milks, creams or gels.

Applications

[00182] According to one embodiment, a composition of the invention can advantageously be provided in the form of a composition for caring for the skin of the body or of the face, in particular of the face.

[00183] According to another embodiment, a composition of the invention can advantageously be provided in the form of a composition for making up keratin materials, in particular the skin of the body or of the face, in particular of the face. [00184] Thus, according to a sub-mode of this embodiment, a composition of the invention can advantageously be provided in the form of a base composition for makeup. [00185] A composition of the invention can advantageously be provided in the form of a foundation.

[00186] Such compositions are in particular prepared according to the general knowledge of those skilled in the art. [00187] Throughout the description, including the claims, the expression "comprising a" should be understood as being synonymous with "comprising at least".

[00188] The invention is illustrated in more detail by the examples and figures presented below. Unless otherwise indicated, the amounts indicated are expressed as mass percentages. Examples 2 to 7 (invention) and Examples 1 and 8 (outside the invention) [00189] The following compositions were prepared.

[00190] [Table 1]

Protocol for preparation of the compositions

[00191] The productions of Examples 1 to 8 were carried out with a Trilab® or Olsa Minilab® type reactor from VMI.

[00192] The temperature was adjusted to 20°C in order to maintain a production temperature of 20°C.

[00193] The elastomer was pre-dispersed under shearing.

[00194] The isododecane was then gradually added to the elastomer until a homogeneous composition was obtained. Trimethylsiloxysilicate was then added, forming the fatty phase. [00195] The macroscopically homogeneous mixture of the phases was prepared by slow introduction of the aqueous phase into the fatty phase at a stirring speed of 4000 rpm for 15 minutes.

[00196] The formula was subsequently degassed under a vacuum bell.

Evaluation of the stability of the compositions [00197] All the compositions of Examples 1 to 8 were packaged in a 30 ml glass jar at ambient temperature (25°C). The stability was observed visually and evaluated at 24 h in accordance with the following criteria:

Stable: The composition is homogeneous without visible phase separation. Unstable: The composition is not homogeneous (visible phase separation). [00198] The results are described below:

[00199] [Table 2]

[00200] Examples 2 to 7 according to the invention, having a product [A]X[B] ranging from 0.07 to 0.21 , made it possible to obtain a pleasant texture, which can easily be taken up and spread on the skin, with a fresh and light sensation during application and good stability over time.

[00201] Examples 1 and 8 outside the invention, having a product [A]X[B] outside the range extending from 0.07 to 0.21 , experienced phase separation after 24 hours and were considered to be unstable.
